Operation of MA4SWx10B-1 Series

Operation of the MA4SWx10B-1 series PIN diode switches is achieved by simultaneous application of DC

currents to the bias pads. The required levels for the different states are shown in the tables below. The control

currents should be supplied by constant current sources. The nominal 40 - 60 Ω pull-up resistor voltage @ J4 and

J5 is usually -1 V for -20 mA and +20 mA for +1 V.
